H. GEORGE SOHUETTE, OF MANITOYNOO, W'ISCONSIE,

STREET-LAM P.

SPECIFICATION forming part of Letters Patent No. 317,215, dated May 5, 1885.

Application filed October 13, 1884.

To all whom it may concern.-

Be it known that I, H. GEORGE SGHUETTE, of Manitowoc, in the county of Manitowoc and State of Wisconsin, have invented a new an d,

IO ject being to allow of a lamp being brought down within the post to an opening near the ground, through which the lamp can be trimmed and filled and then raised again to its position for use.

The invention consists in certain improvements in the elevating devices of that class of street-lamps for which Letters Patent of the United States No. 310,728 were granted me on the 13th of January, 1885, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a vertical section of a lamppost having the lamp-elevator applied to it, and Fig. 2 is a similar view representing a modification. Fig. 3 is a View similar to Fig. 1, but in which the spring-drum is shown in the lower part of the post, the cord passing over a pulley at the top of the post. Fig. 4 is a sectional elevation of an ordinary springdrum, its stop, pawl, and easing, the cord or chain passing around the drum and out through an opening in the casing.

A is the hollow lamp-post, of any usual or desired construction, carrying the lantern B.

c is the elevator, consisting of a round disk or piece of a size to fit loosely in the post, suspended by a chain or cord, d, which connects to a bail, e, on the elevator, and passes upward to a spring-barrel, f, attached at the top of lantern B.

The suspension-barrel f is provided with a coiled spring, which is wound by the unwinding of the chain, and has an automatic brake or stop to hold the elevator at any point. The spring-drum operates as such drums usually do-that is, when the cord is pulled the barrel is revolved, which unwinds the spring. An

(No model.)

upward push on the rod 9 causes the spring to revolve the barrel, thereby winding the cord and raising the lamp. If it is desired to lower the lamp and hold it in any position, the rod 9 is pulled down and held stationary a moment to allow the stop or pawl to engage the teeth of the ratchet-wheel. The end of the stop or pawl is rounded, so that it cannot interfere with the revolution of the ratchetwheel after it has begun to revolve. The spring of the stop or pawl has just sufiicient power to hold the stop or pawl into engagement with the ratchet-wheel when said wheel is stationary; but it will allow the ratchetteeth to pass the pawl when the said ratchetwheel is rotated, such devices being well known and in common use. approved form, or the spring may be arranged simply to balance the elevator and lamp.

To the under side of the elevator is attached a rod or wire, that is long enough to extend to the door h in the side of the post when the elevator is raised. The lamp is placed on the elevator, the latter then raised slightly to release the stop, and the spring then acts to draw the elevator upward, thus bringing the lamp to its proper position in the lantern. The lamp is brought down by pulling on rod 9 until accessible through door h.

These devices can be applied to an ordinary lamp-post. In the modified form shown in Fig. 2 the elevator c is supported on the upper end of a ratchet-bar, 'i, that passes through a slot in a disk or piece, 7c, that is fixed in post A near the bottom of the door-opening. A spring, Z, attached to the post, bears, by its free end, against one edge of bar '5, so as to press the opposite toothed edge into contact with the side of the slot in piece 70, thus holding the bar in any position desired. By pressing back the bar 2' it is released, and may be then raised and lowered, the spring acting as a brake to prevent too sudden a descent.

The suspension-chain may pass over a guide pulley at the top and down to a spring-barrel 9 placed in the lower part of the post. I do not limit myself in that respect.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a hollow lamp- I may use any post provided with a door or opening in its lower portion, of an elevator adapted to carry a lamp and suspended from a spring-barrel for being raised and lowered in the post, substanstially as and for the purpose set forth.

2. The combination, with a hollow lamppost, of an elevator or platform within the post and adapted to carry a lamp, a chain or cord supporting the elevator, and a springba-rrel carrying the chain or cord, as set forth.

3. The combination, with a hollow lamppost, of elevator 0, arranged for movement up and down within the post, suspension chain or cord d, and spring-barrel f, substantially as set forth.
